Sistema de generación de formas de onda de un array de transductores de ultrasonidos basado en FPGA

Abstract

In this final degree thesis, a prototype of a system has been designed to assist in transcranial insonation research. The designed system is capable of generating three-level square waveforms to excite up to 8 (expandable to 16) channels of a multi-beam ultrasonic system to be used in transcranial insonation. These waveforms are burst of square signals that can be configured both in frequency and in the rest of the signal parameters, including the delays between channels, by means of a particular program. In this report are the needs and specifications to be accomplished, with the corresponding solutions adopted, each and every one of them with the most precise justifications on the validity of the same. It is due to these premises that there is an implicit visualization of the system in question, the necessary simulations and tests and, consequently, the final result obtained.
